The strength of well-designed decentralized systems is resiliency. But it's like multithreaded code; it's hard to write. Centralized systems trade off brittleness and kludges for a certain amount of predictability and the ability to actually hire programmers. As a result yes, you can run on multiple AWS sites, but you have to know too much to make that convenient.
And other "benefits" (as the author points out those are two-edged) ("controlable, walled gardenable,defensible, brandable auditable, copyright checkable, GDPRable...") are also by design chokepoints. Its those chokepoints that make it brittle and that is where the weaknesses lie.
Pre-computing: in the 1950s and 1960s there was a public debate as to whether the US government should be descentralized as a way of withstanding nuclear attack. Though we got the highway system, instead the US became more centralized, not less. And as a result it has contributed to more alienation of the populace from their representatives. I long thought California should spread its government around more for more public buy in and support (and for that matter knowledgable opposition). But of course everybody who cares about government wants to be "close to the seat of power", which we see particularly in the federal government.
